Who We Are

With 8.1 million members, Blue Cross and Blue Shield of Illinois (BCBSIL) is the largest health insurance company in Illinois. We started in the height of the Great Depression in 1936 in Chicago and grew out of a shared interest to protect individuals and families from financial ruin related to health care costs. Today, we remain member owned rather than publicly traded. We answer to our members, not to shareholders.

BCBSIL is committed to promoting the health and wellness of our members and communities. Our commitment guides us in fostering greater access to care, working to lower the overall cost of care -- while improving care quality and patient outcomes.

As an innovative leader in the health insurance industry, we have pioneered many ways to move the health care system from one based on fee-for-service – or volume – to one that pays for value and quality outcomes. We have a responsibility to play an active role in keeping health care costs manageable for our members.

We are proud of the level of service our employees deliver for our customers and members. We’re also proud to be fellow Illinoisans who call this state our home. Our business and our company remains strong and growing. Our statewide employee base has increased 33% since 2010 to 10,845 employees. We work in offices across the state, including Downtown Chicago, Rockford, Quincy, Danville, Naperville, Springfield, Jacksonville, Downers Grove and Marion. We are proud to serve our members and are guided by our Purpose: “To do everything in our power to stand with our members, in sickness and in health.”
